14.41 GMT: FC Porto are lining up Barcelona full-back Marc Cucurella as a replacement for Alex Telles, who could be heading in the other direction, according to Diario SPORT.

Telles is out of contract in 2021 and the report claims he's reluctant to extend his deal. Porto, therefore, will look to cash in on him this summer -- pending what happens with football in relation to the coronavirus pandemic -- and Barca are among the teams chasing him. Chelsea are also said to be interested.

The Portuguese club could then turn to Cucurella to replace Telles. He is on loan from Barca at Getafe, who have a €6 million option to make the deal permanent in the summer. They're likely to execute that option but could then look to sell elsewhere. Barca would be entitled to 40 percent of any profit they make.

The confidential document, seen by Reuters, also recommends allowing transfer windows to be changed in accordance with new season dates and urges clubs and players to work together to find solutions to salary payments during stoppages.

The document is due to be discussed by members of FIFA's Working Group later on Thursday. No decision on the issues has yet been taken by FIFA.

The German side have suggested privately they could lose Sancho this summer but will demand a fee of around €130 million for the 20-year-old, who has scored 14 Bundesliga goals this season.

United are at the head of the queue after Solskjaer made the England international one of his primary targets as he looks to revamp his forward line.

Sources have told ESPN that United have become notorious for dragging their feet in negotiations and risk losing out to a rival unless they, according to one source, "get their act together quickly."

11.17 GMT: ESPN FC's Julien Laurens believes that Arsenal striker Pierre-Emerick Aubameyang, linked with Barcelona and Manchester United in recent months, holds all the cards when it comes to his future.

10.39 GMT: Marca is expecting a busy summer at the Bernabeu despite the current suspension of La Liga, outlining "seven pieces of homework" for Real Madrid to resolve before next season.

The paper's front page declares that "signing a goal scorer is a priority" after Luka Jovic has failed to convince, while Madrid are also looking to make decisions on the future of Luka Modric -- whose contract expires in 2021 -- and whether Martin Odegaard should return early from his Real Sociedad loan.

Other items on the agenda are the future of Achraf Hakimi, who has spent the last two seasons at Borussia Dortmund, signing Donny Van de Beek from Ajax, Alphonse Areola continuing as reserve goalkeeper, and whether Dani Ceballos should be sent on another loan or sold.

09.58 GMT: Germany's 2014 World Cup final Mario Gotze has seen his career has come to a standstill, and the midfielder has fallen from grace at Borussia Dortmund.

Talks over a new contract at the Westfalenstadion have long ended and the27-year-old will be available on a free transfer in the summer.

Sport1 reports that Bayer Leverkusen are loosely interested in Gotze, who has also been linked with a switch to Inter Milan.

09.24 GMT: Napoli defender Kalidou Koulibaly has ling been one of Europe's most sought-after centre-backs -- could this be the year he finally makes his big move? If so, he'll have his pick of destinations, according to ESPN FC's Julien Laurens.

Will Real Madrid spark a bidding war for Erling Haaland?

08.41 GMT: Tottenham Hotspur defender Jan Vertonghen has spoken about the big decision he has to make about his future as his contract at the club winds down.

Vertonghen, 32, has just a few months remaining on his Spurs deal, and told Belgian TV show De Kleedkamer that his post-retirement plans will also come into play as he makes a call on what to do next.

"I'm in a process right now that I have to grab a piece of paper and write down the pros and cons of the options I will have soon," he said.

"I will really have to decide what I want in my career. In three to four years, I will normally return to the place where I will likely settle down. "I have to start thinking about where I still want to live, what language I want to learn, what culture I still want to live in.

"And also, very importantly, which competitions and prizes I still want to win. I don't want to regret anything in my career."

Vertonghen has been linked with a move to Inter Milan, where he would reunite with former Spurs playmaker Christian Eriksen, who was also his teammate at Ajax before they moved to Spurs.

08.00 GMT: With a lack of takers for Germany international Kai Havertz amid the coronavirus crisis, the midfielder could remain at Bayer Leverkusen for another season and agree to a new contract with a release clause below €100m, kicker reports.

The Champions League club initially held out for a fee in the €120m region, but already prior to the current crisis Havertz, under contract until 2022, was not subject of a bidding war by European top clubs despite all the 20-year-old's talent.

Although Leverkusen have already spent parts of the planned Havertz windfall, the club, owned by pharmacy giant Bayer, do not fear to run into financial difficulties.

Sporting executive Rudi Voller told kicker: "We have the best German player of the next ten years with Kai. I don't have any reason to worry about Bayer."

The deal will cost them £120 million, a fee that is putting off other would-be suitors including Liverpool, Chelsea and Spanish giants Barcelona and Real Madrid.

Sancho left Manchester City for Borussia Dortmund in 2017 for just £8m, but now it looks as though the exciting attacking winger could return to the city for a far bigger fee. The player himself is said to favour United where he can line up alongside England teammate Marcus Rashford, and where he is guaranteed more game time than, say, Liverpool.

United are desperate to land a marquee signing and they have long courted a player considered one of Europe's hottest properties.

The Mirror suggests that United are willing to spend more than the £89m they paid for Paul Pogba in 2016.

Barcelona are reportedly ready to sell the Frenchman for £90m and United are preparing an ambitious bid. Griezmann has failed to impress at Camp Nou and, despite the fact he's only been there for one season, the club are looking to cash in so they can revamp their squad.

Griezmann was linked with a move to United in 2017 but he instead opted to stay at Atletico Madrid, then under a transfer embargo, until Barca paid his £110m release clause.

But now United are confident of landing a big name and they're willing to dangle the carrot of the famous No. 7 shirt, soon to be vacated by Sanchez, a player United expect to move on permanently.

Aubameyang in 'strong position' to control his Arsenal destiny

Julien Laurens analyses Pierre-Emerick Aubameyang's position at Arsenal given the forward's contract status.

Vidal to join Inter in the summer

Inter were keen to land the midfielder in January but failed as a result of Barca's change in management following the appointment of Quique Setien. However, the situation has now changed. Barcelona need to sell players to lower costs and bolster their own spending funds, and the Chilean would make space for some needed income.

If Vidal goes alone, he is likely to cost between €10-15m, and both player and Inter boss Antonio Conte are interested on the deal going through.
